AYJTQMATEG Ll'Cellrl'llNtit MEANS FOR GAS STOVEEJ.

Application filed September 23 1925.

My iuveiuiou relatesto means tor automatically opcrat' the pilot light, or flasher on a gas stove which is ordinarily now operatmlby hand. The pilot light is ot ordinary well known constructionnow in use. whereby by pressing a button the pilot light is flashed to the luirnors on the gas stove. and then by a separate opera tion turning; on the gas, the hurucr i lit from the pi ot light.

My invention relates to an automatic lighter :tor stoves adapted to ojfierate by the turning ot' the gas automatically in a manner to project the flame from the pilot light to the tumors, lighting: the turned on burner immediately. lhis provides a safeguard to a stove so that the burners caniwt be turned on without the same. This is an important feature of my invention as gas stoves are quite dangerous in the home where there are children, and often the burners are turned on by the child, who, not being aware ot the danger, does not turn on the lighter at the some time that the ga burner is turned on, and thus gas escapes into the home which may become very dan- .I H,'()1lbefore it is apprehended by the parent. and turned off.

\Vith my invention this diiiiculty is entirely overcome as the burner cannot be turned on without lighting the some auto matically. litter the burner valve is opened, by met-ins ot a cam member adjustably connected to the valve, l cause the li rhttuf pilot to be automatically operated momentarily, which is just suilicicnt to flash the lighting flame to the particular burner turned on and thereby automatically lighting; the burner, ove coming: any danger or possibility of the lnirner being; turned on without li erhting it, thus safeguarding the home from asphyxiation by gas when the burners are turned on accidentally by a child or otherwise.

My invention includes means of a simple nature and of an inexpensive design which may be attached to practically any stove now equipped with a pilot lighter, or which can be equipped with a tlasl'ier so that the same may be made to operate automatically, the parts being adjustal'ile to the particular valve and lighter i'itiechanisin. In this manner l nrovide a very practical device for automatically lighting gas burners.

These objects, together with other details and features ot the invention will be more fierial No. 138,412.

(Figure 4: is a side view of my device associated with the gas valve.

Figure 5 is a bottom view of the gas valve and the associating parts of my device.

In the drawings 1 have illustrated a gas stove A, only a portion oi? which is shown, to'illustratc the position of the burners B which are ordinarily lit hv means of matches or may be lit by a pilot light such as C, approximately centrally positioned between the burners and having openings to permit a flame to be flashed or projected to each burner when the pilot light valve 10 is operated. The pilot light illustrated is not shown in its minute detail because it is of any ordinary and well. known construction wherein a small pilot light is employed which burns continuously and which is adapted to flash or project a flame when the valve 10 is pres ed down to open the same.

in the ordinary gas stoves such as A, the burners B are fed by a main supply pipe 11 which extends along the front of the stove and from which the valves 12 project so as to direct the gas to the burners B. These valves 12 are provided with operating handles 13 to turn them on and oil"; The valves 12 are ordinarily :toruied with a lower projecting portion or hank ll: which car-- firmly attached to the shank against the nut 16. Thus when the handle 13 is operated the cam lip 18 is operated so that siniullll taneously with the opening or closing of the valve 12 by the handle 13, the cam lip 18 is operated, the purpose of which will. be here inatter described.

The pilot or flasher C is connected by the teed pipe 20 which leads from the valve to the flasher head 22. while the valve 10 is connected directly to the gas supply pipe 11. The valve 10 n'ovided with an operatii'ig head or button 2 which is ordinarily held by a spring means, not illustrated in the drawings, in practically closed position. lVhen the button 23 is depressed an increase supply of gas is projected through the pipe to the head 22 in a manner to cause the pilot C or flasher to project a flame to each of the burners B. I provide a yoke arm 241 which is adapted to extend over the button 23 and which carries a strap member 25 across the top of the same. The strap member 25 is formed with bifurcated ends that form lips 26 which. may be bent below the button 28 to attach the yoke 241-. firmly to the operating button 23, as illustrated in Figures 2 and 3.

The downwardly depending ends 27 of the yoke 24-. are attached to the operating rod 28 which extends along below the valves 12, and which is positioned adjacent the cam lips 18 which are attached to each of the valves 12 as hereinbetore described. The rod 28 is formed with downwardly depending enter ends 29 which extend through guide members 30 and which carry coil springs 31 above the guide members and at the corner 32 ot the rod 28.

The coil springs 31 assist in holding the rod 28 elevated to normally'hold the valve 10 approximately closed as is ordinarily the case with the pilot light C. The springs 31 are not always necessary as I have found iny'automatic lighter will operate without these coil springs, but I- dosire to illustrate them that it may be clear that such springs may be used to assist in holding the rod 28 out of operating position. The depending end 29 of the rod 28 extends freely through the guide member 30.

l Vhen the valve 12 is operated by the handle 13 the cam lip 18 is caused to rotate into the path of the rod 28 depressing the sainei drawing the yoke 24: downward against the button 23 to flash the pilot C to the burners B. Therefore it will be readily apparent that my automatic gas lighter operates in a very simple effective manner, causing the pilot to operate simnltancously with the valves 12 and not permitting any of the burners to be turned on without light ing the same from the pilot or flasher C.

The operation of the pilot or flasher C is automatic with the operation of the valve 12 and is only momentarily, as the cam lip 18 engages the rod 28 to press the same downward in a manner to operate the button 23 and to automatically release tron'i the rod alter the cam lip 18 has passed over the rod and the burner valve 12 is in open position. The cam 17 with the lip 18 is so positioned in relation to the rod 28 that the valve may be partially closed to turn down the burner without operating the pilot. This is also true in the opening of the burner as it is apparent that none of the valves 12 operate sufficiently to leak gas until they have been turned a certain distance. The cam 17 is adjustable so that it may be proymrly set in relation to the rod 28;

The simple ctiective operation of my automatic lighter for gas stoves is quite apparent and the structure of the same is simple, being readily connectible to the present pilot lights which are now in use on gas stoves of well known construction, so that at a small cost any gas stove can be equipped with my anton'iat-ic lighter means and there by prevent the accidental leakage of gas, because with my lighter when the burner is turned on the gas will be lit. I have found my device to be very practical in use and to be preferred, as it may be operated with a single band not making it necessary to used both hands when the burner is turned on as is ordinarily the case where the ordinary pilot light is nsed. I believe my automatic lighter also saves gas as it only lights the pilot when it is needed and this is meu'ientarily so that only a small amount of gas is consumed in operating the same.

In accordance with the patent statutes I have described the principles of operation of my auton'iatic gas lighter and I have illui-itrated in the drawings a particular attaehn'ient and construction of the same, how ever. t iis is only illustrative oi a means o'l oarrvinp out my invention and it is apparent that it may be applied to uses other than those above set torth and carried out. by other means within the scope oil the :t'ollowing claim.

I claim:

n ligl'iter for gas stoves having burner valves and a pilot light valve. comprising a vertically movable longitudinally disposed rod, a loop fastened to said rod having a tlat portion which is adapted to rest upon said pilot light valve and support said rod therefrom and means carried by &ach of" said burner valves tor depressing and releasing said rod during operation of said burner valves in one direction.
